Title: CVT with motor/generators having stators moved by worm wheel and worm screw
Inventor: MOELLER FRANK
IPC: B60K6/26
Filed: 2008-02-06
Abstract: A transmission system of continuously variable transmission ratio includes an epicyclic gearset, an input shaft 28, an output shaft, first and second electric motor/generators comprising rotors 2, 4 and stators 6, 8, 12. Stator 8 is arranged to be axially moveable and is positioned on one side of the rotor 4 while stator 12 is positioned on an opposite side of the rotor 4. The stator 8 is fixed to an annular support 16 having helical formations or female screw threads 18 which mesh with male screw threads 20 on a spigot 22 that is stationary and connected to stator 12. An actuator (74, fig 4), via a worm screw 26 meshing with a worm wheel 24 formed on support 16, rotates the stator 8 relative to the spigot 22, thereby moving the stator 8 in an axial direction with respect to the rotor 4. This movement increases or decreases an air gap between the stators 8, 12 which is optimised for the motor/generator operating conditions. One or both motor/generators may be of the axial flux type and the actuator (74) is controlled by a controller.

Title: Improvements in Turning Ploughs.
IPC: A01B63/28
Filed: 1918-06-18
Abstract: 123,257. Fowler & Co., J., and Royston, M. H. June 18, 1918. Ploughs.-A plough for ploughing in stretches is provided with two separate underframes, separately adjustable vertically, which are fitted with inthrowing right and left hand plough bodies respectively. The underframes e, e<1> are each supported at the front end by a wheel f vertically adjustable by a screwed spindle f<3>, and at the rear end by wheels or by lateral projections on nuts g' riding on screwed spindles g<1> mounted in brackets carried by rods g extending downwardly from the main frame a. The rods g are arranged to prevent lateral displacement of the rear end of the frames e, e<1>. The forward end of each frame may be adjusted laterally by inserting a pin h<1> which connects the frame to a drag-bar h, vertically slidable in slots in plates k, in the desired one of a series of perforations in a bracket h<2> at the forward end of the frame. The underframes are raised out of work by turning the main axle d either by the pull of the chain l attached to the ordinary turning lever b when the implement is turned or by clutching the axle to the wheels n when the implement is travelling. The clutch mechanism is of the kind described in Specification 4514/96. A cataract cylinder s as described in Specification 19006/07 is fitted to damp the descent of the frame. The axle d is provided at each end with two arms t, one attached to the front end of the corresponding underframe by a chain u and the other by a chain v to a bell-crank lever connected by a short chain to a transverse bar w<1> to which the frames e, e<1> are attached. To prevent backward rotation of the pivot wheel in turning, the periphery of a circular rack o secured thereto is provided with teeth o<1> adapted to be engaged by a pawl having a tail connected with the shaft p' of the clutch device so that the action of lifting the frames locks the wheel. A plough y may be fitted for making an open furrow between the two underframes.

Title: Improvements in or relating to electric attenuators
IPC: H03H7/24
Filed: 1954-04-07
Abstract: 763,641. Attenuators. GENERAL ELECTRIC CO., Ltd., and EASTER, B. April 6,1955 [April 7, 1954], No. 10216/54. Class 40 (8) An attenuator for high-frequency energy of the order of tens of megacycles per second comprises a two - conductor transmission line of uniform characteristic impedance and a series of attenuation pads of the same impedance each of which may be switched into the line. The attenuator is mounted to lie within an elongated rectangular block 1 of duralumin, of which Fig. 7 shows the cross-section and Fig. 6 a part longitudinal section containing one attenuator pad 18, 18, 19. A shallow longitudinal groove 3 forms one conductor of the transmission line whilst a further groove 6, opening into the groove 3, forms a housing for the series resistors 19 of all the pads. The shunt resistors 18 are accommodated within insulated holes 7 communicating at one end with the groove 3 and at the other with a further groove 14 which accommodates conducting members 54 connecting one end of each resistor 18 to the metal block 1. The pads A to E are arranged to provide attenuations respectively of one, two, two, five, ten db. and are each associated with a switch 20. The sections F and G are each provided with two switches 20 and comprise respectively two and four 10 db. pads. The switches 20, Fig. 4 (underside shown), are of the wafer type and are mounted side-by-side overlying the groove 3, tags 25, 26 of adjacent switches being soldered together. Since the two switches associated with the section G are of necessity spaced apart, a length of conductor (Fig. 5, not shown) is provided to bridge the gap between the connecting tags. The tag 25 of the first switch and the tag 26 of the last switch are connected respectively to the inner conductors of input and output coaxial sockets 16 (input only shown). The outer conductors of the sockets are connected to the metal block. The movable members 22 of switches 20 carry conducting bridges 37 which, when the switches are in the first position (as shown), connect together the tags 25, 26 of each switch. In this position the tags 25, 26 and the bridges 37 form with the groove 3 a continuous two-conductor transmission line. When the movable member 22 of a switch is slid to its second position the connection between the tags 25, 26 is broken and the tags are connected through the movable contact members 32, 31 respectively to the terminals 28, 27 of one of the series resistors 19. In this position the contact members 32, 31 form with the groove 3 short lengths of transmission line of characteristic impedance equal to that of the main line. A cover 57 is arranged over the switches 20. The switches may be actuated individually by knobs 43 or may be ganged together by a cam-and-lever mechanism. This mechanism is designed to operate simultaneously the pairs of switches 20 associated with the sections F and G. The resistors 18, 19 may be of carbon or nichrome. Values for the resistors are given in the Specification.

Title: Improvements in or relating to radio receivers
IPC: H04B14/00
Filed: 1971-04-21
Abstract: 1298169 Amplifiers LICENTIA PATENT VERWALTUNGS GmbH 21 April 1971 [28 July 1970] 10372/71 Heading H3T In a receiver suitable for use in a wideband transmission system for frequency modulated signals compensation for frequency response fluctuations caused by fluctuations in the received radio field is effected by means of a network which is inserted in an amplifier of the receiver. The network comprises a transmission line L of length equal to a whole number of half wavelengths #/ 2 , # being the wavelength of the centre frequency of the band of frequencies and a resistance R and diode D in shunt across lengths of the line which differ by #/ 2 . The arrangement is intended to compensate for changes in frequency response brought about by the action of automatic gain control, e.g. of the type using variable-impedance shunt diodes in a transistor amplifier. As shown it compensates for increase in highfrequency response with increase of signal strength, but the reverse effect may be produced by interchanging the diode and resistor (Fig. 4, not shown).
